#Formula for area of a rectangle how to

Therefore, the rectangle area will equal the sum of the area of these two triangles. The given rectangle diagonal is divided into two equivalent right-angled triangles. Why Area of the rectangle is length x breadth? So, Area of a Rectangle = Breadth (⎷(Diagonal) 2 - (Breadth) 2). Therefore we can write this formula as ⎷((Diagonal) 2 - (Breadth) 2) × Breadth. We know that, formula to calculate the area of a rectangle is Length × Breadth. Now, we can find the diagonal of a rectangle using the Pythagorean theorem. There are two diagonals in a rectangle of the same length. Step 3: Give your answer in square units.Ī rectangle diagonal is a straight line inside the rectangle connecting its opposite vertices.Step 2: Find the product of the length and breadth values.Step 1: Note the length and breadth measurements from the given data.Follow the steps below, for finding the area of a rectangle

How to Calculate the Area of a RectangleĪ area of a rectangle is equal to its length times its breadth (or width). The main difference between a square and a rectangle is that the length and breadth are the same for a square. In the case of a square, the area becomes the side2. By multiplying the length and width, the area of the rectangle gets the dimension of square units. Once its length and breadth are known, the area of any rectangle is calculated. The perimeter and content of the rectangle are therefore given by:

We cannot calculate for a rectangle because it is a two-dimensional figure. Lateral and total surface areas can only be calculated for three-dimensional figures. The area of a rectangle can be calculated in units by multiplying the length of the rectangle by breadth (or width). The formula for finding the area of a rectangle depends on its length and breadth.

But in the case of a square, since all the sides are equal, the area of the square will be equal to the square of the length of the side.

So we can say that the area bounded by the perimeter of a rectangle is its area. Whereas when we talk about the perimeter of a rectangle, it is equal to the sum of all its four sides. Therefore, the formula for the area of a rectangle is equal to the product of the length and breadth of a rectangle. The area of a rectangle depends on its sides.
